在此之前我搞了一天，虽然seata好用，用起来也超级简单，但是安装配置是真的麻烦，遇见了各种坑，下面来进入正题。o(╥﹏╥)o
一 . 版本
注意：如果版本不匹配也会有各种报错，可以根据官网匹配版本。
seata：1.3.0
alibaba.cloud：2.2.3.RELEASE
nacos：2.0.2
二. docker安装搭建seata服务端
2.1 下载seata镜像
docker pull seataio/seata-server:1.3.0
2.2 在Linux目录下创建registry.conf，我的路径在/data/seate/registry.conf，接下来的所有创建都在这个目录下
cd /data
mkdir seate
vim registry.conf
2.3 registry.conf中的内容如下
registry {
type = "nacos"
nacos {
application = "seata-server"
serverAddr = "127.0.0.1:8848"
group = "SEATA_GROUP"
namespace = ""
cluster = "default"
username = ""
password = ""
}
}
config {
type = "nacos"
nacos {
serverAddr = "127.0.0.1:8848"
namespace = ""
group = "SEATA_GROUP"
username = ""
password = ""
}
}
注意registry和config需要在同一个组下,注册中心我用的是nacos，注意nacos的地址要改。
----->>>这里我插一句，需要新建一个数据库seata，并且新建三张表，
-- -------------------------------- The script used when storeMode is 'db' --------------------------------
-- the table to store GlobalSession data
CREATE TABLE IF NOT EXISTS `global_table`
(
`xid` VARCHAR(128) NOT NULL,
`transaction_id` BIGINT,
`status` TINYINT NOT NULL,
`application_id` VARCHAR(32),
`transaction_service_group` VARCHAR(32),
`transaction_name` VARCHAR(128),
`timeout` INT,
`begin_time` BIGINT,
`application_data` VARCHAR(2000),
`gmt_create` DATETIME,
`gmt_modified` DATETIME,
PRIMARY KEY (`xid`),
KEY `idx_gmt_modified_status` (`gmt_modified`, `status`),
KEY `idx_transaction_id` (`transaction_id`)
) ENGINE = InnoDB
DEFAULT CHARSET = utf8;
-- the table to store BranchSession data
CREATE TABLE IF NOT EXISTS `branch_table`
(
`branch_id` BIGINT NOT NULL,
`xid` VARCHAR(128) NOT NULL,
`transaction_id` BIGINT,
`resource_group_id` VARCHAR(32),
`resource_id` VARCHAR(256),
`branch_type` VARCHAR(8),
`status` TINYINT,
`client_id` VARCHAR(64),
`application_data` VARCHAR(2000),
`gmt_create` DATETIME(6),
`gmt_modified` DATETIME(6),
PRIMARY KEY (`branch_id`),
KEY `idx_xid` (`xid`)
) ENGINE = InnoDB
DEFAULT CHARSET = utf8;
-- the table to store lock data
CREATE TABLE IF NOT EXISTS `lock_table`
(
`row_key` VARCHAR(128) NOT NULL,
`xid` VARCHAR(96),
`transaction_id` BIGINT,
`branch_id` BIGINT NOT NULL,
`resource_id` VARCHAR(256),
`table_name` VARCHAR(32),
`pk` VARCHAR(36),
`gmt_create` DATETIME,
`gmt_modified` DATETIME,
PRIMARY KEY (`row_key`),
KEY `idx_branch_id` (`branch_id`)
) ENGINE = InnoDB
DEFAULT CHARSET = utf8;
实现分布式每个业务库都要加一张表undo_log，不然会报错，
CREATE TABLE `undo_log` (
`id` bigint(20) NOT NULL AUTO_INCREMENT COMMENT '主键',
`branch_id` bigint(20) NOT NULL COMMENT 'branch transaction id',
`xid` varchar(100) NOT NULL COMMENT 'global transaction id',
`context` varchar(128) NOT NULL COMMENT 'undo_log context,such as serialization',
`rollback_info` longblob NOT NULL COMMENT 'rollback info',
`log_status` int(11) NOT NULL COMMENT '0:normal status,1:defense status',
`log_created` datetime(6) NOT NULL COMMENT 'create datetime',
`log_modified` datetime(6) NOT NULL COMMENT 'modify datetime',
PRIMARY KEY (`id`),
UNIQUE KEY `ux_undo_log` (`xid`,`branch_id`)
) ENGINE=InnoDB AUTO_INCREMENT=9 DEFAULT CHARSET=utf8 COMMENT='AT transaction mode undo table';
2.4 创建推送配置文件 vim config.txt，是将文件中的配置推送到nacos中去。
service.vgroupMapping.btb_tx_group=default
store.mode=db
store.db.datasource=druid
store.db.dbType=mysql
store.db.driverClassName=com.mysql.cj.jdbc.Driver
store.db.url=jdbc:mysql://172.0.0.1:3306/seata?useUnicode=true
store.db.user=root
store.db.password=root
store.db.minConn=5
store.db.maxConn=30
store.db.globalTable=global_table
store.db.branchTable=branch_table
store.db.queryLimit=100
store.db.lockTable=lock_table
store.db.maxWait=5000
注意btb_tx_group需要与客户端保持一致,顺便注意数据库驱动，如果是8以上用我的这个驱动，5.7的用com.mysql.jdbc.Driver
2.5 创建推送脚本，因为执行脚本要在config.txt的下一层，所有加一层目录
mkdir sh
cd sh
vim nacos-config.sh
内容如下：最好不要有任何的修改

echo "========================================================================="
if [[ ${failCount} -eq 0 ]]; then
echo " Init nacos config finished, please start seata-server. "
else
echo " init nacos config fail. "
fi
2.6 执行推送脚本，后面是nacos的ip地址，如果端口不是8848还需要加一个-p 8884你的端口
bash nacos-config.sh -h 127.0.0.1
2.7 创建容器，注意SEATA_IP如果是阿里云服务器需要写外网ip
docker run -d --restart always --name seata-server -p 8091:8091 -e SEATA_IP=172.0.0.1 -e SEATA_CONFIG_NAME=file:/data/seata/registry -v /data/seata:/data/seata seataio/seata-server:1.3.0
三 . 客户端（也就是微服务，项目中使用seata）
3.1 pom.xml 引入依赖
<!-- seata分布式事务-->
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-alibaba-seata</artifactId>
<exclusions>
<exclusion>
<groupId>io.seata</groupId>
<artifactId>seata-spring-boot-starter</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>io.seata</groupId>
<artifactId>seata-spring-boot-starter</artifactId>
<version>1.3.0</version>
</dependency>
注意这里一定要剔除原来自带的 io.seata包，并且服务端和客户端的包版本要一致。
3.2 配置项目配置文件
#seata
seata.application-id=${spring.application.name}
seata.tx-service-group=btb_tx_group
seata.config.type=nacos
seata.config.nacos.server-addr=172.0.0.1:8848
seata.config.nacos.group=SEATA_GROUP
seata.registry.type=nacos
seata.registry.nacos.application=seata-server
seata.registry.nacos.server-addr=172.0.0.1:8848
seata.registry.nacos.group=SEATA_GROUP
注意：这里的btb_tx_group要跟服务端的vgroupMapping后面的key保持一致，
如：service.vgroupMapping.btb_tx_group=default
3.3 加入注解使用
扩展： 我用的是一个数据库，执行报错，说我缺少主键，于是我在表undo_log加了一个增的主键id，上面的创建undo_log表的sql是我加了id的，官方给的是没有id的。请知晓！！！！
问题：单数源是有报错的，原因是因为我是一个数据库，需要设置代理配置如下 ，根据自己实际情况是指配置文件，不然会报错
#单数据源
seata.enable-auto-data-source-proxy=true
#多数据源
seata.enable-auto-data-source-proxy=false
